Apple Final Cut Pro 7 - Manual (Page 242)

3 Enter a number of frames in the Frame Offset number field.
Frame offset can be any whole number between 0 and 30. The default value is 4. For
example, if a video monitor connected to your DV camcorder shows your program four
frames later than your computer display, a frame offset of 4 will synchronize the two.
Note: Depending on your external monitor configuration, you may need to experiment
with frame offset values to synchronize the external monitor and the computer display.
4 Click OK.
5 Play your video in the Canvas or Viewer and compare the video offset between your
external monitor and your computer display.
6 If the computer display and external monitor are still not synchronized, repeat steps 1
through 5 using different frame offset values until the display and monitor are in sync.
Note: Final Cut Pro automatically compensates for latency in third-party audio cards if
proper Mac OS X Core Audio drivers are provided.
Troubleshooting External Video Monitoring Problems
If you experience problems while viewing your sequence, there are a few things you can
try.
To quickly choose a different video interface for external monitoring
Do one of the following:
µ
Choose Final Cut Pro > Audio/Video Settings. In the Summary tab, choose a video interface
(or none) from the External Video pop-up menu, then click OK.
µ
Choose View > Video Playback, then choose a video interface.
If you cannot see video on your external monitor, try the following:
• Choose View > Refresh A/V Devices to update the list of connected devices.
Note: This is especially useful if you just connected an audio or video device without
quitting Final Cut Pro.
• Choose View > External Video > All Frames (or press Command-F12).
• If you are using a third-party video interface, check the cable connections between the
video interface, breakout box (if applicable), and video monitor.
• If you are using FireWire and DV, check the FireWire connection between your computer
and VTR (or other DV FireWire device) and the cables between the DV device and the
external monitor.
• Make sure output connectors are always connected to inputs, and vice versa.
• If your monitor has multiple inputs, make sure the proper input is selected on the front
panel of the monitor or in the monitor’s onscreen menu.
